Location has quickly moved into the mainstream of the (mobile) Web and it continues to be a strong driver of applications and research activities. The general appeal and usefulness of geo-located data (e.g., for information access with freely available mapping services) are only some of the reasons for its fast rise.
After the initial boost and consolidation of approaches based on the simple use of geospatial coordinates, we now see an increasing demand for (i) more sophisticated systems, (ii) stronger retrieval, mining, and analytics solutions, and (iii) more powerful semantics.

LocWeb 2018 will continue a successful workshop series at the intersection of location-based services and Web architecture.
It focuses on Web-scale services and systems facilitating location-aware information access as well as on Spatial Social Behavior Analytics on the Web as part of social computing.

The location topic is seen as a cross-cutting issue equally concerning information access, semantics and standards, social analysis and mining, and Web-scale systems and services. The workshop is an integrated venue where location and spatio-social aspects can be discussed in depth with an interested community. We aim for a highly interactive, collaborative full day workshop with ample room for discussion and demos that will explore and advance the topic, with contributions from research and industry.
New application areas for Web architecture, such as the Internet of Things (IoT) and the Web of Things (WoT), will lead to increasingly rich and large sets of applications for which location is highly relevant as the connection to the physical world. Location has high importance in Web-based designs, and it continues to provide challenging research questions.

The objective of the workshop is to bring together a community of researchers at the intersection of location and the Web, under the main topic of spatial social behavior, location-aware information access and Web-scale systems. LocWeb addresses location as a cross-cutting issue in Web research and technology that connects the online world to the physical spatial world. It examines location aspects in the domains of social computing, search, analytics, mobility, apps, services, standards, and systems.

The aspect of social computing will have a particular focus on spatio-social networks, i.e., social network users' behaviors, activities, interactions, news propagation, and social influence learning models in the context of available spatial or location information in social media and the Web.
We are particularly interested in new tools and techniques for the modeling and analysis of dynamic spatio-social networks, besides static spatio-social networks.
One hurdle has been the disconnect between activities in the online and physical worlds. We welcome work to understand this disconnect and develop methods and techniques to bridge this gap. Users with similar interests, profiles and behavioral patterns but different locations may be subject to very different influences on their decision making. We are particularly interested in what additional knowledge can be mined from dynamic spatio-social graphs.
This concerns areas of data mining, web mining, and natural language processing to develop more efficient and practical algorithms and models to obtain knowledge from spatio-social media and web data.
Focusing on static and dynamic spatio-social networks allows to understand how people are influenced by social interaction in their daily life decision, e.g., travel, flight booking, hotel recommendation, purchases, etc. These are highly related to social communications as well as their locations, and online social users' interaction combined with the availability of their locations provides an opportunity for researchers and practitioners to contribute to this challenging problem.

The workshop will provide a topic-specific and interdisciplinary venue where researchers from different Web-related fields can discuss and develop the role of location.
It will aid them in identifying common issues across different fields and from different perspectives, to learn about new approaches, and discuss open issues. The workshop aims to serve as a unique venue to integrate different backgrounds, and to stimulate the exchange of ideas and closer cooperation. It is also highly interactive and collaborative, with ample room for discussion and demos that will explore and advance the geospatial topic in its various relevant areas.

LocWeb will solicit submissions under the main theme of Web-scale Location-Aware Information Access and spatial social computing. Subtopics include (i) geospatial semantics, systems, and standards; (ii) large-scale geospatial and geo-social ecosystems; (iii) mobility; (iv) location in the Web of Things; and (v) mining and searching geospatial data on the Web. The workshop encourages work describing Web-mediated or Web-scale approaches that build on reliable foundations, and that thoroughly understand and embrace the geospatial dimension.

We solicit full papers of 6-8 pages, and short papers of up to 4 pages describing work-in-progress or early results. Authors are invited to submit original, unpublished research that is not being considered for publication in any other forum.

Workshop submissions will be evaluated based on the quality of the work, originality, match to the workshop themes, technical merit, and their potential to inspire interesting discussions. The review process is single blind, so please provide your name and affiliation.

Please submit to the Locweb workshop through the easychair WWW satellites at https://easychair.org/conferences/?conf=www2018satellites and select "Eighth International Workshop on Location and the Web" as the track.

Submissions should follow the styles and guidelines of the WebConf conference proceedings.

Accepted workshop papers will be published in the WWW companion proceedings and the ACM Digital Library.

For inclusion in the proceedings, at least one author of the accepted paper has to register for the workshop and present the paper.

Presenters are encouraged to bring demos to the workshop, to facilitate discussion and make the workshop more interactive.
